FIELD OF THE INVENTION
This disclosure generally relates to a cross-linked aminosiloxane polymer that includes an intramolecular structure having a particular chemical formula. This disclosure also provides a method of forming the cross-linked aminosiloxane polymer.
BACKGROUND OF THE INVENTION
The desire to have hair retain a particular shape is widely held. The two methodologies of accomplishing this are permanent chemical alteration of the hair or temporary alteration. A temporary alteration is one which can be removed by water or by shampooing. This has generally been accomplished by means of applying a composition to dampened hair after shampooing and/or conditioning and prior to drying and/or styling. The materials used to provide setting benefits are resins or gums and are sold in the form of mousses, gels, lotions, or sprays. However, these materials tend to increase difficulty with combing the hair, degrade hair feel, and can be difficult to work with. Accordingly, there remains an opportunity for improvement.

This disclosure provides a cross-linked aminosiloxane polymer including a first siloxane backbone, a second siloxane backbone, and at least one intramolecular structure. The intramolecular structure cross-links a silicon atom of the first siloxane backbone and a silicon atom of the second siloxane backbone. The intramolecular structure has the chemical structure:




In structure (I), X is chosen from the following groups:





In groups (II), (Ill), and (IV), each R is independently a C1-C10 hydrocarbon group. Each R1 is independently a C1-C10 hydrocarbon group.

EXAMPLES
Other components that may be used for purposes of this disclosure are described in PCT/US15/024905 and PCT/US15/024886, each of which is expressly incorporated herein by reference in one or more non-limiting embodiments. The following examples are intended to illustrate and not to limit the invention.
Example 1A: Formation of Cross-Linked Aminosiloxane Polymer at 0.33 Mol Ratio
To an 8 oz. reaction vessel the following components were charged: 2.57 g of a 5 Dp pendant aminopropyl siloxane and 0.44 g of maleic anhydride along with 3.00 g of d-chloroform. This reaction mixture was heated in a 55° C. water bath for 5 hours producing a viscous, slightly yellow liquid. In the proton NMR spectrum set forth in the bottom of FIG. 1, there is a lack of sp3 protons, which would have resulted from the Michael addition of the aminosiloxane at 4.52 ppm, and the presence of sp2 protons at 6.91 ppm.
Example 1B: Formation of Cross-Linked Aminosiloxane Polymer at 0.21 Mol Ratio
To an 8 oz. reaction vessel the following components were charged: 1.79 g of a 5 Dp pendant aminopropyl siloxane and 0.21 g of maleic anhydride. This reaction mixture was heated to a higher reaction temperature of 70° C. for 2.5 hours. The reaction product is a viscous, slightly yellow liquid. In the proton NMR spectrum set forth in the top of FIG. 1, there is an appearance of the sp3 proton resulting from the Michael addition of the aminosiloxane at 4.52 ppm, and the partial consumption of sp2 protons (from the same carbon) at 6.91 ppm.
Example 2: Formation of Cross-Linked Aminosiloxane Polymer at 0.25 Mol Ratio
To an 8 oz. reaction vessel the following components were charged: 49.09 g of a pendant aminopropyl siloxane of the structure (MD94DA6M; where “A” is an aminopropyl group) and 0.91 g of maleic anhydride. This reaction mixture was heated in an isothermal oven at 70° C. for 2.5 hours. The reaction product is a firm, extensively cross-linked gel that is optically clear with no detectable amine odor. Results of frequency modulation experiments (depicted in FIG. 2) provide evidence for cross-linking through comparison of the storage modulus (G′) and loss modulus (G′′) where the G′ is higher than G′′ for a cross-linked aminosiloxane polymer. Results of temperature sweep experiments (depicted in FIG. 3) provide evidence for cross-linking through comparison of the storage modulus (G′) and loss modulus (G′′) where the G′ is higher than G′′ for a cross-linked aminosiloxane polymer.
Example 3: Formation of Cross-Linked Aminosiloxane Polymer at 0.33 Mol Ratio
To an 8 oz. reaction vessel the following components were charged: 48.80 g of a pendant aminopropyl siloxane of the structure (MD94DA6M) and 1.22 g of maleic anhydride. This reaction mixture was heated in an isothermal oven at 70° C. for 2.5 hours. The reaction product is a firm, extensively cross-linked gel that is optically clear with no detectable amine odor. Results of frequency modulation experiments (depicted in FIG. 4) provide strong evidence for cross-linking through comparison of the storage modulus (G′) and loss modulus (G′′).
Example 4: Formation of Cross-Linked Aminosiloxane Polymer at 0.23 Mol Ratio
To an 8 oz. reaction vessel the following components were charged: 1.26 g of itaconic anhydride and 58.74 g of a 100 Dp pendant aminopropyl siloxane. This reaction mixture was heated in an 80° C. water bath for 5 hours producing a gel. In the frequency sweep set forth in FIG. 5, the product is confirmed as cross-linked as the storage modulus (G′) is greater than the loss modulus (G′′).
